Definitions

  • This invention concerns a two-function coil-forming assembly according to the preamble of claim 1.
  • the invention concerns a coil-forming assembly suitable to cooperate with a drum forming coiled bundles of wire having a diameter ranging from 10 to 20 mm. or greater.
  • Such wire is produced by hot-rolling and comes from a rolling line positioned upstream.
  • a proposal in the name of the present applicant exists according to which two pairs of headstocks, of which each pair comprises a pre-bending Garrett headstock and an Edenborn headstock, are provided in a cooling line at the sides of a Garrett-type turret forming coiled bundles.
  • These units feeding the turret that forms coiled bundles are fed by channels which feed rolled stock and comprise suitable switching means.
  • the present applicant has now shown that it is possible to overcome the shortcomings of the above proposal and to arrange for the coil-forming unit to be in direct, immediate cooperation with the turret or drum forming the coiled bundles and at the same time to work with feeder units having different individual functions.
  • Such feeder units may consist of an Edenborn-type headstock or a Garrett-type pre-bending assembly.
  • a first advantage is the fact that, when the rolled stock feeder units are in their working position, they can cooperate with the Garrett-type drum at a position immediately upstream thereof without any substantial break in continuity, thus enabling the coils to be positioned at once in a required manner.
  • the invention enables the coiled bundle to be readily discharged by means of a simple lateral movement of the individual feeder unit working at that moment.
  • the invention enables the coiled bundles formed in a substantially known manner to be swiftly and easily handled.
  • the rotatable column having a substantially vertical axis and bearing at least two different individual feeder units is included in close cooperation with the Garrett drum, whereby such feeder units can consist of an Edenborn headstock and a pre-bending Garrett assembly.
  • the two different individual feeder units are positioned substantially at 180° opposite to each other on the rotatable column.
  • these different individual feeder units consist of two Edenborn coil-forming headstocks and two pre-bending Garrett assemblies.
  • This embodiment of the variant permits that,while one individual feeder unit is working, its twin individual rolled stock feeder unit can undergo maintenance without any need to halt rolling therefor except possibly for a very short time.
  • each different individual feeder unit is secured to the rotatable column in such a way that it can be oriented and can therefore be rotated by a required angle in relation to the working position.
  • This variant enables the Garrett drum to be freed momentarily from any encumbrance above it at the end of formation of a coiled bundle, thus allowing a movable plate to rise and lift the coiled bundle so that suitable engagement forks can take the bundle and discharge it onto a removal conveyor.
  • two drums forming bundles can cooperate with the position of formation of the coiled bundles so that, when a drum holds a formed bundle, it is displaced for removal thereof while the other drum to form coiled bundles takes the place of the first drum.
  • a feeder assembly or two-function coil-forming assembly 10 comprises a rotatable column 11 having a substantially vertical axis.
  • Rotary actuation of the rotatable column 11 and its positioning in a desired specific position are performed with a known system suitable for the purpose.
  • the rotatable column 11 cooperates with at least one Garrett drum 20, which in this case comprises a known movable plate 21 able to lift a coiled bundle 22 when formed and bring it up to the level of a removal conveyor 24.
  • the rotatable column 11 cooperates with channels 14 and 15 respectively feeding rolled stock belonging to the ranges of rolled rods having sections in the low range and high range of the field of sections envisaged, which covers sections of about 10 mm. in diameter up to 20 mm. or more in diameter.
  • Each of the feed channels 14-15 cooperates respectively with a different individual feeder unit 25 when the feeder unit is in its working position.
  • the feed channel 15 cooperating with a pre-bending assembly 13 in avoiding any danger of contact when the pre-bending assembly 13 is in its inactive position or when it is moving to that position may comprise a retractable portion or element 16 which frees the zone taken up when functioning is taking place in a known manner.
  • the feed channel 15 feeds the rolled stock thereto, and the rolled stock is taken, pre-bent, fed onwards and delivered by rollers 17.
  • the different individual feeder units 25 are secured to the rotatable column 11.
  • one of the individual different feeder units 25 consists of an Edenborn coil-forming headstock 12, while the other is a pre-bending Garrett assembly 13.
  • the different individual feeder units 25, being an Edenborn coil-forming headstock 12 and a pre-bending assembly 13, can be oriented by a jack 18, for instance, on the axis of the inclined arm attachment 19.
  • This jack 18 is anchored to the rotatable column 11 and to the feeder unit 25.
  • the coil-forming headstock 12 and the pre-bending assembly 13 can take up an inactive position 26 and a coiling and working position 27.
  • the feeder units 25 when they are in their working position 27, they can take up a first working or coiling position 27 and a second position 127 for removal of coiled bundles.
  • This second position 127 is such that it frees momentarily the upper part of the Garrett drum 20.
  • orientation of the feeder units 25 can also be achieved by acting on the rotatable column 11.
